- IMPROVEMENT IN CURTAIN-FIXTURES.

Specification forming part of Letters Patent No. 187,523, dated February 20, 1877; application tiled December 21, 1876.

To ali whom it 'may concern.:

Be it known that I, JAMES DoUeHER'rY, ot' New York city, in the county and State of New York, have invented a new and Improved Carriage-Curtain Fixture, ol' which the following is a specication lFigure 1 is a top view, Fig. 2 a front view, and Fig. 3 an end View, ofv my improved earriage-curtain fixture.

Similar letters of reference indicate corresponding parts in all the figures.

rlhis invention relates to an improved combination of the parts that constitute the detcnt or click of a spring carriage-curtain. It consists in pivoting the detaining-pawl within a slot in the shank ofone of the curtain-holding` posts, so that it will be in line and parallel with the back of the roller, and in causingl it to engage the edge of a ratchet Wheel, which is mounted upon one end ofthe curtain-roller.

By this construction a simple and reliable detent mechanism is obtained, which, although on the outside oi' `the roller, is practically out of sight, and does not involve any complicated, construction of roller or of post-head, as in eases where the detent is placed within the roller or caused t0 bear against the end of the same.

In the drawing, the letter A represents a curtain-roller, hung by projecting gudgeons in brackets or hangers B and G, that-are rigidly secured to the carriage-frame or other device. The roller A is a spring-roller--that is,

The hanger G, adjoining the disk a, has a horizontal slot in its shank or body between its 'point of attachment and the axle of the roller D, and through this slot is inserted the detent or pawl d, which is parallel and in line with the back of the roller, as in Fig. 1., and bears with one end against the edge of the disk a, as is also clearly shown in Fig. 1. By a pin, e, the pawl is pivoted in the slotted hanger C. A spring,f, crowds the pawl against the edge oi' the disk a.. r1he outer end ot' the pawl d carries an eye, in vwhich a cord, g, is secured, said cord passing through a loop .or eye, h, that is attached to the side of the hanger C, as shown. When the curtain is unwound the pawl will click into the teeth ot' the ratchetwheel, and hold the spring wound up; but when, by means of the cord g, the pawl is pulled off the disk a, the spring within the' notched disk a, and bracket B, with the'bracket C, which is slotted between itspoint of attachment and the axle ot' the roller, `and with the pawl d, which is parallel and in line with the back ot' the roller, and pivoted in said slot ot' the bracket, substantially as and for the` purpose herein shown and described.

JAMES DOUGHERTY.
